I have had chronic sinus problems all my life. Is there some way you can support your immune system? Drugs are just a temporary fix. If I go outside I start sneezing. Air conditioning stops my headup, especially if I sit near a register or in a car. Low pressure weather systems effects my sinuses. The biggy for me is emotions. If I get upset, then two days later I come down with a sinus attack. If you find a cure, send a private message.
